IMPROVED FOLDING, MATTRESS.

Specilication forming part of Letters Patent No. 92,396, dated July 6,1869.

, in the art to make and use the same, reference being had to theaccompanying drawings, forming part of this specification, in whichdrawings- Figure l represents a longitudinal section of this invention.Fig. 2 is a transverse section of the same. Fig. 3 is a plan or top viewof one section thereof, the stuffing and covering having been removed toexpose the parts below.

Similar letters indicate corresponding parts.

This invention relates to a spring-mattress composed of three sections,which are connected by hinges in such a manner that one of the endsections folds over and the other under the middle section. The springsat the edges of the various sections are supported at the bottom bywooden slats, and they bear at the top against pieces of webbing, whichare stretched from corner to corner, being secured at their ends tocorner-blocks in such a manner that the edges of each section becomesoft, aswell as the central parts thereof, and thereby a foldingspring-mattress is obtained which is light, easily handled, and ofsuperior convenience.

Each section of my mattress is constructed of a frame, A, made of datslats, as shown. These slats are connected by a series of webbings, B,running in a transverse direction, and by another series of webbings, C,running in a longitudinal direction, and from each corner of said framerises a block, D, and the several blocks are connected by webbings E F,as shown in Fig. 3. The webbings B Cform the support for the middlesprings, G, and the edge springs H rest on the slats of the frame,

| and their tops bear against the webbings E F,

which connect the corner-blocks. Apiece, I, of canvas or other suitablematerial, extends over all the springs, and this piece of canvas formsthe bottom for the stuffing J. By this arrangement the edges of eachsection are rendered elastic, as well as the center, and amattress isobtained which is very comfortable, and also very light and easy tohandle.

My entire mattress consists of three sections, K L M, which are.connected together by hinges f g, so that the section K folds over andthe section M folds under the middle section, L.

The hinges f are secured to the corner-blocks D of the sections K L, andthe hinges g to longitudinal slats of the frames A of the sections L M,as shown in Fig. l, and if the mattress is unfolded, the hinges f, beingclose to the edges of their respective sections, do not interfere withthe comfort of the person lying on the mattress.

My mattress folds up in a small compass, it is very light, the woodenframe being reduced to the smallest possible weight, and it can be usedwith advantage in a common bedstead or in a bureau-bedstead, such asthat for which Letters Patent have been granted to me February 18,1868.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

A series of mattresses consisting of frames A., composed ofcorner-blocks D, webbings B C E F, and springs G H, and upholstered attop and :dat at the bottom, and alternately hinged to each other aboveand below, whereby the sections may be folded uniformly on each otherand extended as a continuous mattress, and all parts are constructed andarranged to operate as described.
